great to here 273 lover....I have been waiting for someone to ask that question .... the answer is because I like to be the underdog and I proved it with a few of my buddies built 340 360 and 380 horse magnum engines in dart duster and barracuda . you just have to spin the engine a little higher and they will rev LOL. they still think it's not a 273 engine. I love the small block engine !
